At Titusville now. I have also found HAI to be proffeshional. I have flown / trained in 2 other countries. There is the usual US situation of having low time instructors, but to be fair they are good. The CFI program is very thougher and the Check pilots and Cheif ensure high standards and uniformity in training. As you can already fly, there is no problem anyway. I have flown in Cali' also which is great but more expensive than FL. The only down side is the lack of elevated terrain, which isn't great. This place may not have every thing, but it has a lot. A good choice.
The FAA use HA for recurency and of course the UK's Bristow primary training for the North Sea is done there also!
PM if you have q's
